[yt-users] Perspective Camera / Spherical Projections

[Matthew Turk]

Hi Munier,

In the past, the allsky projections were doing this using HEALpix
projection.  PerspectiveCamera is designed to somewhat adjust the
vectors fed in to the volume renderer to be perspective-based rather
than orthographic.  I think the concept was to keep it as API
compatible as possible.
